Schaumburg has that nice forest preserve across from Woodfield mall that can provide nice backdrop and loads of parking.
Also, I have invited a sales manager from a local BMW dealer to come along as a second photographer. Will let you know of his availability.
I had a Lexus IS prior to the F30 and a bunch of Lexus IS folks got together for fun and eventually turned it into a big annual gathering of Chicagoland Lexus owners, with local dealerships sponsoring the event. Just a thought.
